What is Glycosylation?
Glycosylation refers to the enzymatic procedure that attaches glycans (sugar molecules) to proteins or lipids. This amendment is necessary for protein folding, stability, and serve as. There are two predominant types of glycosylation: N-linked and O-connected.
N-Linked Glycosylation
In N-associated glycosylation, glycans attach to the nitrogen atom of asparagine residues in a protein. This category is accepted in lots of secreted and membrane-certain proteins.
O-Linked Glycosylation
O-linked glycosylation comes to attaching glycans to the hydroxyl group of serine or threonine residues. This form is frequently came upon in mucins and different secreted proteins.
